Application 'filed January 10, 1918. Serial No. 211,2 76.

To aZZ whom it may concern:

Be it known that Josnrrr DAIN, late a citizen of the United States, and a resident ofMoline, in the county of Rock Island and State of Illinois, did invent certain new and useful Improvements in Clevises for Tractors, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention'relates to tractor hitch arranged so as to be adjustable, for purposes hereinafter described, and adapted'more particularly. for connecting plows with a tractor. The'ob ject of my invention being to provide a device that is simple and effective in operation and which is adjustable while the operation of plowing is in progress.

Referring to the drawings in which similar numerals indicate identical parts- Figure 1 is a side elevation of the rear portion of a tractor showing my device mounted thereon.

Figure 2 is a bottom ure 1.

Figure 3 is a transverse sectional detail on the line 3-3 of Figure 1. Figure 41 is a detail of the brake, and Figure 5 is a detail in part section of the lever. and connected parts.

"I have shown in the drawings sufficient of a tractor necessary to fully illustrate the applicationof my invention. The tractor frame consists preferably of channel bars '1.

and 2, connected at their rear ends by transverse plate 3 which form a support for the seat of the operator. 7 g 6 are rigidly'mounted on the frame bars 1 and 2 respectively for the support of anaxle 7 on'which is mounted, to freely revolve thereon. a wheel 8 having lattice spokes 9 on both sides securely riveted. together and to thetire ofthe wheel. On each. side of the wheel 8 and secured to the spokes 9 are spokes 10 extending radially from hubs 11; the ends of the spokes 10' are projected outwardly and to the outward projec tions are secured sprockets 12, suitable bolts 13 passing through the rims thereof, the 'ends of thcspokes 10, and the spokes 9, holding the parts rigidly together. The hubs 11 are fitted with roller bearings '14, the latter being held in placeby thebearings 5'and' 6, which project within a counter sunk portion ofthe hubs 11, and washers 15 plan view of Fig- Bearings 5 and which are retained in position'by acylindrical member 16, the inner ends of the hubs being countersunk for the washers 15 and the ends of the cylindrical member 16. Stay bolts 17 extend from side to side of the wheel 8 and are secured to the spokes 10, adding to the rigidity of the structure.

Extending outwardly from the bearing 5 is a projection 18 on which is pivotallymounted a lever 19 which is adapted to engage with any one of a'series of notches 20 in the edge of a hood 21 covering the wheel 8. Integral with the lever 19, and extend ing downwardly. therefrom is an arm 22. A yoke shaped hitch element 24 formed of two forwardly extending arms connected by a transverse hitch bar, has the end of one arm hooked, to move. freely, in a downwardly projecting arm in the bearing 6; the opposite arm is permanently hooked to the arm 22 of the lever 19. Both arms of the yoke terminate 'in substantially the same plane. I

The element 24: extends horizontally rearward where it is supported by chains 25 secured-at opposite sides thereof and adapted to engage with hooks 26 secured on the frame bars 1 and 2 to facilitate mounting. When an implement-or other object to be drawn is attachedto the hitch element 24, the links of the chains 25 are usually adj'usted upon the hooks 26 so the chains will be slack when said element is under tension, in order that said element will be free to rise and fall and permit relativevertical movement between the tractor and the im .plement, due to inequalities in the ground As before stated the ltch element 24: is, hookedin an arm 23 forming at that point a stationary pivot, and as the opposite end 7 of the element 2 1 is engaged with the arm 22 0f the lever 19, below the .pivotof the latter, is follows that, by operating the'lever l9gthe hitch element2 1 can be swung onfits mslly di. ected cm the brake mechanism a1 conncctihle thereto at the will. of theopeistor. V

A. stub shaft is jUlH'DRlQLl inthe projeo tion 18 which is bored for that piirpose, On. the outer end of the stub shaft 28 is mounted an arin29 having,' in its free end a notch 30. 'Rigidly mounted on tlie inner end of the stub shaitQSis cam 31. Inside the sprocket 12 adjacent'itraine bar 1 is stud 32 mounted on a projection 33 of the bearing. 5. Friction banos 3 1 having one of their ends bent to clasp the studfii and secured thereon by a cotter 35, are disposed within the sprocket and are ladapted to be moved at will into contact with the inner suritace of the sprocket rim by the cam 31 when the latter is turned, the cam 31 normally having its smaller diameter l'ietwecn and in contact with parallel ends of the triotion hunts it bolt 86 passes-tln-oughthe parallel ends of the frictionbands sense has confined in one end a coil spring 37 which exerts its force against the adjacent end of one of the friction hands ZAJand a nut on the end of the bolt.

A latch. of a common type, is provided on the lever 19, and includesa dog 33 which is adapted to engage with the notch 30 in the arm 29 when it is desired. to operate the brake; l i

before explained the hitch element 24 swung by operation of the lever 19; when it becomes necessary to; apply the'brake the lever is inoved until the dog-{=38 is engaged wi'h the notch 30 in the arm 99, then a.

' iC jl siniultane'ousiy rock the cam 31; spreac k inst the sprocket i -on to retard the speed o; of tne'wheel 8: i I do not 'c'h'nllne the specific construction of tlie bralie shown, as dillerent types ot bra lies: may be employed and operated at .vill by the same lever which controls the lateral movement of the hitch element 24.

'What I claim i i 1. "A draft devicefor tractors, comprising a rigid yoke shaped 'hitch "element horizon-1 any disposed sue having its ends' pivotally 1e lever being: nor

supported at opposite points on a tractor, and means to swing said element laterally on one of its pivoted ends.

2. In a draft device for tractors, the com- 'bination of a rigid yoke shaped hitch'elen ent pivotally supported on the tractor to swing both vertically and laterally, a lever pivotally supported on the tractor and c0nnected to the hitch element and operable to swing said el'einent laterally.

In a draft device for tractors, the combination of a rigid yoke shaped hitch element pivotally supported on the tractor to swing both vertically and. lstein-ally alever.

is adapted to be swung laterally by operation of the lever.

5.111 adra'lit device for tractors, the combination of a hitch element pivotally s'up-.

ported on the tractor, a lever pivotally supported on the tractor and connected to said element and operable to swing saideleinent laterally, 'a brake for one of the tractor wheels and means to operate said brake siinultaneouely with the lateral swing oitthe element.

6. In a draft device for tractors, the coinbination oi a hitch element pivotally' supported on opposite sides oi? the tractor, a brake. lever pivotally supported on the tractor and permanently connected to the hitch element and ment laterally, and. ineans' to connect the brake with said lever at will whereby the brake is operated simultaneously with the lateral swing; of said element.

h A draft device for tractors comprising supported at their tront ends on the tractor' adjacent the, transverse vertical Eplane of said supporting. element, and means to adjust. one of said arms longitudinally. to positively. swing the transverse bar of; theyoke andlockit in adjusted position.

oerahle to swing said ele ported on the tractor and'longitw' 9.

10. The combination with a tractor having in the central longitudinal vertical plane thereof an element positioned relatively near the ground surface, a vertically swinging hitch device con'iprising two bars at the sides of and extending backward from the cen trally positioned tractor element, a transversely positioned bar connecting the two aforesaid bars. and means for positively moving one of the longitudinally arranged bars longitudinally of the tractor and for looking it under adjustment.

1 The combination with a tractor, of the frame thereof, a tractor element positioned near the ground surface, a transversely arranged hitch bar, tivo longitudinally extending bars rigidly connected to the hitch bar and pivotally mounted at their ends on the frame in the transverse vertical plane of the tractor element and means on the tractor for positively moving the hitch bar transrersely and longitudinally.
